Muscular System

Regular Contact lenses ahere to the cornea of the eye with natural eye lubrication- nothing else is required, usually.

Intraocular lenses are small corrective lenses implanted behind the iris of the eye and in front of the the lens of the eye to correct myopia and hyperopia.

When you contract your bicep, the tricep is relaxed as it is intended to resist against a force in the complete opposite direction. As it is relaxed, it stretches because the insertion point of the muscle in the forearm experiences a pull and the tendon is stretched around the bend of the elbow. There may be a very small contraction in the tricep, to stabilise the contraction of the bicep.

Yes it is

Workout on ur back. The back takes up 70% of your upper body muscle. It makes you look huge too.

Cerebellum

Type your answer here... 90 pounds

Smooth for a+ kids. This means you too dom!

No a heart does not have bones inside it .

You have gastrocnemius and soleus muscles on the back of the leg. They have common insertion in the form of tendocalcaneus. On the front side you have muscles of peroneal compartment to antagonize the calf muscles.

The lungs are attached to the heart. The heart carries deoxygenated blood through the pulmonary artery to be converted to oxygenated blood in the lungs. The oxygenated blood returns to the heart through the pulmonary veins.

rectus femoris

well there are lots of muscels in the human head but im not sure how many for certain as i am only 12 years of age please could you write to me if you no or could find out the answer thanks CHARLIE

The nervous system controls muscles and glands by electrical impulses.

tendon (fibrous tissue) connects muscles to bones

I know what mine is but not all are as fortunate

Scalene muscles(anterior & middle fibers) can entrap the lower trunk of the brachial plexus, causing neuropraxia of ulnar nerve

Yep! Your foot has tons of little muscles in it. It can happen a lot during exercise-especially swimming where you foot is rotating and contorting a good deal.

yes it does because you took to much so either take a little bit or dont take any at all yeah just dont take any at all thanks for readind bye!

NO! your muscle does not turn into fat it just replaces it as you work out. the toning and mass of your muscle will decrease though witch will make your muscle "shrink" even if you dont work out extensivly you still need to do some kind of physical activity to maintain the muscle you have gained.

Groups of muscles are defined by their location on the body and the function that they perform e.g. the quadriceps are grouped due to the their location on the femur and they are all responsible for the extension of the knee joint.

Longitudinal and circular muscles. These are known as antagonistic muscles, meaning that one relaxes whilst the other contracts.

FOP can cause this but not in healthy people.

Unique anatomical feature of the Heart muscle is the presence of intercalated discs. They hold the heart cells together and allow the conduction of impulses between the cells. Also cells have a high quantity of mitochondria, for the provision of energy.

Cardiac muscle uses aerobic respiration which is rich in myoglobulin, glycogen, and very large mitochondria that fills over 25% of the cell. Skeletal muscle only 2% of the cell. In turn makes cardiac muscle highly resistant to fatigue.
